Hacking ATMs with a Purpose

Link to September 9 San Jose Mercury News article, "Silicon Valley's Barnaby Jack hacks ATMs for the love of it".

Excerpt: Jack was back home in San Jose between trips in a summer of trips, including one in July to the Black Hat computer security conference in Las Vegas. That's where he achieved rock star status by demonstrating how he hacked two different models of ATMs and turned them into cash-spewing wonders.

The idea is not to rob banks blind, but to let the machine manufacturers know what bad guys could do if they worked at it as hard as Jack did. To that end, Jack experimented on two machines he bought online and shared his findings with the ATM manufacturers before he shared them with the world. Both manufacturers instituted fixes before Jack's presentation.
